It aint an ST so yeh no sure about the scuff plates, that said though, they look damn great!
The pedals however are a lil cheap looking and clearly dont fit properly. The aluminium bit is too big for the ****y accelerator pedal and doesnt fit its curvature, you may want to look for comething smaller that fits into the curved contour of the pedal itself. I made the same mistake and had to take my first set of pedals back (Just said that they didnt fit). Mine look almost stock. Heres a Pic, I know its manual but they made my pedals for auto as well..
Mate, but if you like the look of your pedals, than Keep em! Dun listen to me!
